JACOB P. HOLLENBEGK, OF FREDERICK, OKLAHOMA.

OIL-GAS BURNER.

T 0 all whom it may concern."

Be it known that I, JACOB P. HOLLEN- BECK, citizen of the United States, residing at Frederick, in the county of Tillman and State of Oklahoma, have invented certain new and useful Improvements in Oil-Gas Burners, of which the following is a specification.

My invention relates to oil burners and particularly to that type of oil burner in which steam is injected with the oil into a generating chamber for the purpose of securing a more perfect combustible gas.

The primary object of my invention is to provide a very simple, effective, easily operated and easily cleaned oil burner of that type in which jets from the gas generating chamber are used to heat water in the reservoir and thereby create steam to be injected into the generating chamber.

A still further object is to provide a construction in which the steam is superheated and then carried to the gas generating cham ber to be mixed with the oil.

A. still further object is to provide a construction in which the steam after it passes from the steam superheating chamber will act to more fully atomize the oil coming from the supply pipe and thus break up the particles of oil, thus securing a more perfect gasification of the fuel and a more complete and uniform intermingling of the particles of steam with the particles of oil.

My invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of one form of my improved burner. Fig. 2 is a vertical transverse section thereof. Fig. 3 is a horizontal section on the line 3-3 of Fig. 2. Fig. 4 is a view similar to Fig. 3 but showing a modified form of burner in which two steam superheating chambers are provided, and Fig. 5 is a transverse section of Fig. 4 on the line 55 thereof.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

Referring now more particularly to Figs. 1, 2 and 3, 2 designates the base, this base being hollow to provide a water reservoir and steam generator 3 which is connected by a supply pipe to any suitable source of supply. Supported above the base 2 and in spaced relation thereto is a gas generating chamber composed of the trough 4 hav Specification of Letters Patent.

passage of gas and the gas is ignited at these.

perforations.

The gas generating chamber is supported in spaced relation to the steam generator or base and for this purpose I have provided the base with the upwardly extending lugs 10 at opposite ends of the base and provided the bottom of the trough 4 with the downwardly extending pairs of ears 11 adapted to fit over the lugs 10. One end of the trough 4 preferably rests upon an upwardly extending flange 12 at one end of the base 2. The other end of the base is also provided with an upwardly extending flange 13, but the gas generating chamber is less in length than the base, and hence an air passage is provided between the gas generating chamber and the flange 13 as illustrated in Fig. 1. This provides for an inlet of air to the burners which heat the water in the reservoir or water chamber 3. Both sides of the upper plate of the base 2 are provided with the upwardly extending flanges 14 which are however, relatively low in comparison with the flanges 12 and 13, thus providing for the outlet of flames between the flanges 14 and the adjacent wall of the gas generating chamber for a purpose to be later stated.

The trough 4 forming the bottom of the gas generating chamber is provided with a plurality of nipples 15. These nipples project up into the generating chamber and also project down below the bottom of the trough 4 toward the upper plate of the base 2 as at 17. These nipples 15 are for the purpose of conducting the gas from the generating chamber and projecting the gas in the form of burning jets against the top of the steam generator. The gas generating chamber is also provided with nipples 16 which also extend through and project below the under face of the bottom of the trough 4 and carry off and lower the level of the surplus oil, where the oil accidentally has such depth within the chamber 4 as to cover the top of the nipples 16. In normal circumstances, however, whatever oil is within the chamber 4 will be below the level of the tops of the nipples 15 or 16.

Water is admitted to the steam generator 3 by means of a conducting pipe 18 provided with a regulating valve 19, while oil is admitted to the gas generating chamber by means of an oil intake pipe 20 provided wit-h a valve 21. This oil intake pipe is connected by a pipe 22 to the steam space of the reservoir 3. This pipe 22 preferably extends from a steam superheating chamber 23 which is connected to the steam space of the water reservoir.

Preferably, and as illustrated in Figs. 1

and 2 the superheating chamber 23 is formed as part of the base 2 and is provided with openings 24 leading into the upper portion of the water reservoir 2 above the water line there-of. The chamber 23 is formed by coring out the material from which the base and the superheating chamber are made. The'pipe 22 extends from the upper portion of the superheating space 23 and extends preferably over the top of said superheating chamber and then downward and laterally where it joins the pipe 20. The superheated steam passing through the pipe 22 is ejected into the pipe 20 and acts to spray the oil and steam into the generating chamber.

The operation of this form of my invention is obvious.

Oil is admitted through the pipe 20 until it covers the bottom of the gas generating chamber and overflows through the nipples 16 and 15 onto the top of the steam generator 3. The oil is then ignited and the flames extending up on each side of the gas generating chamber tend to vaporize the oil in the chamber and create gas, at the same time of course, tending to heat the water in the chamber 3. As the gas is formed it issues through the nipples 15 and is projected against the top of the water reservoir, heating the same and causing steam to be formed. This. steam, in the construct-ion illustrated in Figsl and 2 passes into the'superheater 23. The flames which pass upward from the upper face of the reservoir between the gas generating chamber and the superheater will reheat the steam in the superheater and this dry, heated steam passes by means of the pipe 22 into the pipe 20, and as before stated, projects the mixed steam and oil into the gas generator chamber. The gas which is evolved in the generator is lighted at the openings 8 and 9. It is to be understood that while I prefer to use the su )erheater, I do not wish to limit myself'to tiis use. It will be seen that the pipe 22 is connected to the steam space of the steam generator by means of the superheater. I

The particular form of my device which is shown in Figs. 1, 2 and 3 is intended to be used for ordinary stoves. Where, however, a greater amount of heat is desired I increase the steam space and double the capacity of the superheater by adding another superheater on the opposite side of the burner from the first named superheater. Such a construction is illustrated in Figs. 4 and 5. In these figures 25 designates the steam generator and 26 the oppositely disposed superheating chambers which are formed integral with the water reservoir and extend upward on either side thereof. The upper plate 27 of the steam generator is formed to provide a fire-pan, as previously described, and is provided with the upwardly extending end-flanges 28 and the side flanges 29, corresponding to the flanges 12 and 14-, respectively. It is also provided wit-h the oppositely disposed lugs 30. The gas generator is precisely the same as that areviously described and comprises the boily portion 31 provided on its under side with the oppositely disposed pairs of spaced lugs or cars 32 fitting over the lugs 30. A cover section 33 fits down into the trough shaped body portion as previously described, and is provided with a plurality of perforations. In this form of my invention I have shown three bands of these perforations 34-. Like the gas generating chamber previously described, the gas generating chamber in this form of my invention is likewise provided with a plurality of tubular nipples 35, whereby the jets of gas may be directed against the steam generator. One or more of these nipples is less in height than the remaining nipples, so as to form means for conducting off surplus oil when the burner is primed. There are two superheating chambers 26 one on each side of the steam chamber 25 and having openings 36 connecting the two. The upper end of one superheater is connected by a pipe 37, to one end of the gas generating chamber while the other superheater is connected by a pipe 38 to the other end of the gas generator through the pipe 39, which is provided with the valve 40. The dry steam passing into the pipe 39 forces the fuel into the gas generator in the form of a finely divided spray. This spray of mingled gas, steam and oil is met by the spray of dry steam coming from the pipe 37 and this collision of particles tends to more fully mix the steam and oil and form a more uniform gas, thus giving a greater efiiciency to the burner. The base which forms the water reservoir and steam chamber and the superheating chamber are preferably cast in one piece and these parts are provided with openings whereby the interior of the water reservoir and the superheating chamhers may be cleaned out when desired.

1 have found in practice that my invention is ,very effective, and is capable of giving a great amount of heat in proportion to its size. The burner is very simply constructed, may be easily taken apart as there are no delicate parts to get out of order and it is capable of very easy cleaning. It may be applied to any ordinary stove, furnace or like heater.
